Abstract

Alpine ski boot comprising an outer shell, in which an inner slipper is placed, the shell being constituted by a shell base incorporating at least one rear cover which pivots on the shell base around a transverse axis to a pivoted open position and vice-versa, while the inner slipper comprises a rear tongue extending upward. The upper part of the rear tongue is held attached to the upper part of the rear cover by at least one connecting slide device.

What is claimed is: 
     
       1. Alpine ski boot comprising an outer shell (1) in which an inner slipper (2) is placed, said shell being constituted by a shell base (3) comprising at least one rear cover (5) which pivots on said shell base around a transverse axis (6) between a closed position and an open position, said inner slipper comprising an upwardly extending rear tongue comprising a rear upper portion (15) connected to an upper part (16) of said rear cover (5) by connection means (17) comprising means (29, 290, 20'a, 20'b) causing said rear tongue (13) to pivot when said rear cover (5) pivots around said transverse axis (6), said connecting means comprising sliding means (28, 19, 18) constituted by a vertical groove (19) delimited laterally by two lateral walls (20a, 20b) which cooperate with a pin (28) comprising a head (29) having a diameter greater than a width of said groove, said groove (19) being provided on a central part (200) of a catch plate (18) attached to said rear upper part (16) of said rear tongue of said slipper, while said pin (28) projects to an inside of said shell so as to cooperate with said groove. 
     
     
       2. Alpine ski boot according to claim 1, wherein said connection means (17) comprises downward stop means (28, 26) for said rear tongue (13) restricting rearward pivoting of said rear cover. 
     
     
       3. Alpine ski boot according to claim 1, wherein said groove (19) is located on said rear upper portion (15) of said rear tongue (13) of said slipper, while said pin (28) is attached to said upper part (16) of said rear cover (15). 
     
     
       4. Alpine ski boot according to claim 1, wherein said groove (19) is located on said upper part (16) of said rear cover (15), while said pin (28) is attached to said rear upper portion (15) of said rear tongue (13) of said slipper. 
     
     
       5. Alpine ski boot according to claim 1, wherein said central part (200) of said catch plate (18) comprises two lateral walls (20a, 20b) cooperating with an edge (290) of said head (29) of said pin (28). 
     
     
       6. Alpine ski boot according to claim 5, wherein said catch plate (18) is made of a material which is more rigid than a material of said inner slipper.
